The narrow pink line is coming from your magenta toner/drum cartridge. You may be able to open the from cover and look at the 4 toners. If you look at the magenta (like pink) cartridge, you might see the thin line on the drum surface.
The multicolored band that sometimes shows up on your prints is most likely the transfer belt unit. This is caused by an area of the belt that is not being cleaned very well. This probably tends to show up when you are running mutilple prints of a page.
So it looks like to may need to replace your magenta toner and look at getting a transfer belt unit.

The line could be caused by contamination on the black laser lens. Try using the cleaning wand located in the front door to clean the lens. You will need to remove the waste toner container to access the wand slots. If that does not solve the problem, the black developer housing may need to be replaced.

This can be any of rthe following depending on the position iof the lines on the page. You need to establishe the position of the lines relative to the top of each page and this determines which of the following component will cause the problem

Dirty or damaged developer roller.
Dirty or damaged charging roller.
Dirty or damaged cleaning roller.
Dirty or damaged developer DSD wheels. These wheels are located on the outer ends of the color toner cartridge and appear as a black bushing.
Dirty or damaged transfer roller.
Dirty or damaged transfer drum.

A technique to improve print quality is to try and clean the cartridge nozzles. You may clean the cartridge by following the steps given below:
1. Go to the "Lexmark solution center." This can be done by clicking on "Start," go to "Programs" and Lexmark printer group. Click on the "Lexmark Solution center." Next click on the "Maintenance" Tab. 2. Select "Clean and Fix Horizontal streaks." Click on "Print". This will produce a printed page.
The colors that you should see here are black, yellow, magenta (a reddish purple) and cyan (a dark sky blue). You should notice the diagonal lines above and below the solid horizontal lines. These diagonal lines should be solid from left to right with no gaps.
If there are gaps in the lines or the print diminishes across the page, you should run the "Clean Print Nozzle" page a couple more times to try and clear it up. If you still have gaps at the top and bottom, you should "wick" the cartridges by following the steps given below:
1. Please open the "Solution center" again and go to the "Maintenance" Tab. 2. Select "Install color/black cartridge" and remove the cartridge or cartridges from the printer. 3. Get a damp paper towel. 4. Set the ink cartridge right side up on the damp paper towel so that the ink nozzles are against the towel and hold the cartridge in this position for about 15 seconds. 5. Now wipe the print head (on the bottom where the ink comes out) across in one direction only (left to right) until it looks clean. 6. Next dab the cartridge on the towel to make sure that the ink is flowing. 7. Snap the cartridges back into the printer. 8. On your computer, select "Old Cartridge install." 9. Repeat the "Clean Nozzle Page" one more time. If this fails to address the problem the entire procedure may need repeating.

Try printing one colour at a time - Black, Cyan, Yellow or Magenta.

If when printing, there is no line across the pages, so you need to clean the optics mirrors and exposure glass.
If the line appears in both 1 and 2 mentioned above, you have the fuser roller or drum damaged.
If the line appears in all colour prints, check the fuser or transfer belt.
If it happens only with one particular colour, check that drum unit.
